Mongoose Movies

Introduction

Everyone likes celebrities, right? Well, even if you don't, now is your chance to create your own, better, fictional celebrities! Let's create an Express app with all the basic CRUD actions that will allow the user to create their own celebrities and edit them as they see fit.

The user should be able to:

1. See the list of celebrities
2. See the details of a celebrity
3. Add new celebrities
4. Update existing celebrities
5. Delete celebrities

But wait! That's not all!

Once we have our celebrities, we need something for them to do! Let's make up some movie ideas for our celebrities to star in.
That means we'll need all the basic CRUD actions for movies as well.

The user should be able to:

6. See the list of movies.
7. See the details of a movie.
8. Add new movies.
9. Update existing movies.
10. Delete movies.\

Requirements

• Fork this repo
• Clone this repo

Submission

• Upon completion, run the following commands:

$ git add .
$ git commit -m "done"
$ git push origin master

• Create Pull Request so your TAs can check up your work.

Instructions

Iteration 0 | Initialize the project

After forking and cloning the project, you will have to add a .env file:

PORT=3000

And you have to install all the dependencies:

$ npm install

Now you are ready to start 🚀

Iteration #1: The Celebrity Model

Once we have generated our Express app, our first step is to create the Celebrity model and seed some initial celebrities in our database.

The Celebrity model should have:

• name - String (like Tom Cruise, Beyonce, Daffy Duck, etc.)
• occupation - String (what the celebrity does, why they are famous. For example actor, singer, comedian, or you can put unknown if your celebrity is someone like Kim Kardashian)
• catchPhrase - String (every celebrity needs a good catch phrase. Well maybe not all of them have one in real life, but all of our celebrities will have a catch phrase. This can be pretty much anything)

Steps we will follow in this iteration:

1. Create the celebrity.js model file in the models/ folder.
2. In the celebrity.js model file:
   • Create the Celebrity model with the schema.
   • Create the celebrity schema with name, occupation and catchPhrase.
   • Export the Celebrity model.
3. Create the seeds.js file in the bin/ folder.
4. In seeds.js file:
   • Create an array of 3 objects, each with name, occupation and catchPhrase for our initial celebrities.
   • Call the Celebrity model's create method with the array as argument.
   • In the create method's callback, display feedback.
5. Run the seed file with node to seed your database.
6. Check the database with the mongo command to confirm that your data was saved.

Iteration #2: Listing Our Celebrities

Now that we've got some celebrities in the database, we can start working with them in our Express app. Let's display a list of all the celebrities.

Here's the route we will be using:

Route	HTTP Verb	Description
/celebrities	GET	Show all celebrities

Steps we will follow in this iteration:

1. Locate the /celebrities GET route in routes/celebrities.js.
2. In the route callback:
   • Call the Celebrity model's find method to retrieve all the celebrities.
   • If there's an error, call the route's next function and return the error.
   • If there isn't an error, render the celebrities/index view.
   • Pass the array of celebrities into the view as a variable.
3. Create the celebrities/ folder inside views/.
4. Create the index.hbs view file inside the views/celebrities/ folder.
5. In the views/celebrities/index.hbs view file:
   • Add an <h2> tag for the page's heading.
   • Use a forEach loop to display tags with each celebrity's name.
6. In the views/index.hbs (homepage) file:
   • Add a link that goes to the /celebrities route.

Iteration #3: The Celebrity Details Page

We've got a list of celebrities that displays each of their name, but what if we want to see the other details? In our views/celebrities/index.hbs view with our list of celebrities, let's add links so that the user can click on any celebrity's name, and go to a page specifically for that celebrity. On this page, we will show all the details of that celebrity.

Here's the route we will be using:

Route	HTTP Verb	Description
/celebrities/:id	GET	Show a specific celebrity

Steps we will follow in this iteration:

1. Create the /celebrities/:id GET route in routes/celebrities.js.
2. In the route callback:
   • Call the Celebrity model's findOne or findById method to retrieve the details of a specific celebrity by its id.
   • If there's an error, call the route's next function and return the error.
   • If there isn't an error, render the celebrities/show view.
   • Pass the variable with the celebrity's details into the view.
3. Create the show.hbs view file inside the views/celebrities/ folder.
4. In the views/celebrities/show.hbs view file:
   • Add an <h2> for the page's heading.
   • Display tags with the celebrity's name, occupation and catchPhrase.
5. In the views/celebrities/index.hbs view file:
   • As part of the loop that displays each celebrity's name, add a link that goes to the /celebrities/:id route with the :id replaced by the actual celebrity's id.

Iteration #4: Adding New Celebrities

Now that we have a list of celebrities, as well as a personalized details page for each celebrity, let's make it so the user can add new celebrities to the database

Route	HTTP Verb	Description
/celebrities/new	GET	Show a form to create a celebrity
/celebrities	POST	Send the data from the form to this route to create the celebrity and save to the database

Steps we will follow in this iteration:

1. Locate the /celebrities/new GET route in routes/celebrities.js:
2. In that route's callback:

• Render the celebrities/new view.

3. Create the new.hbs view file inside the views/celebrities folder
4. In the views/celebrities/new.hbs view file:
   • Add an <h2> for the page's heading.
   • Add a <form> tag that makes a POST request to /celebrities.
   • Add <input> tags inside the form so the user can fill in values for each attribute of the celebrity. Make an input for name, occupation, and catchPhrase
   • Add a <button> tag in the form so the user can submit the form once they are done filling it out.
5. Locate the /celebrities post route in routes/celebrities.js.
6. In that route's callback:
   • Create an object with keys for name, occupation, and catchPhrase.
   • Values for those keys should come from the form (req.body is the object full of the values from the form)
   • Create an instance of the Celebrity model with the object you made in the previous step
   • Call the save method to save the new celebrity to the database
   • If there is an error, render the celebrities/new view so the user can try again.
   • If there is no error, redirect to the page with the list of celebrities
7. In the views/celebrities/index.hbs view file:
   • Add a link that goes to the page you just created with the form to create a new celebrity.

Iteration #5: Deleting Celebrities

Now that we have a list of celebrities, a celebrity details page, and a page to create new celebrities, we only have 2 features left to implement: editing celebrities and deleting them. Since deleting is simpler, let's start with that.

Route	HTTP Verb	Description
/celebrities/:id/delete	POST	Delete a specific celebrity

Steps we will follow in this iteration:

1. In the views/celebrities/index.hbs file:
   • As part of the loop, add a <form> tag that makes a POST request to celebrities/:id/delete where the :id is replaced by the actual ID of each celebrity.
   • Add a <button> tag inside the form so that it can be submitted.
2. Create the /celebrities/:id/delete POST route in your routes/celebrities.js file
3. In that route's callback:
   • Use the Celebrity model's findByIdAndRemove method to delete the celebrity by its ID.
   • If there's an error, call the route's next function and return the error
   • If there is no error, redirect to the list of celebrities page.

Iteration #6 (Bonus): Editing celebrities

Final piece of our CRUD puzzle: editing existing celebrities.

Here are the routes we will be using:

Route	HTTP Verb	Description
/celebrities/:id/edit	GET	Show a form to edit a celebrity
/celebrities/:id	POST	Send the data from the form to this route to update and save the celebrity from the database

Steps we will follow in this iteration:

1. Create the /celebrities/:id/edit GET route in routes/celebrities.js.
2. In that route's callback:
   • Call the Celebrity model’s findOne or findById method to retrieve a specific celebrity by its id.
   • If there's an error, call the route's next function and return the error.
   • If there isn't an error, render the celebrities/edit view.
   • Pass the variable with the celebrity’s details into the view.
3. Create the edit.hbs view file inside the views/celebrities/ folder.
4. In the views/celebrities/edit.hbs view file:
   • Add an <h2> tag for the page's heading.
   • Add a <form> tag that makes a POST request to /celebrities/:id with the :id replaced by the actual celebrity's id.
   • Add <input> tags inside the form for each attirbute of the celebrity.
     • Bonus: When you render the edit form, make sure each of the input fields is pre-filled with the current value of the attribute for that celebrity
   • Add a <button> tag inside the form so that the user can submit the form once they are done editing.
5. Locate the /celebrities/:id POST route in the routes/celebrities.js file.
6. In that route's callback:
   • Create an object with keys for each attribute of a celebrity (celebrity has 3 attributes. What were they again? Look back and review if you forgot.)
   • Values for those keys should come from the form submission (req.body).
   • Call the Celebrity model’s update method and use the celebrity's id to specify which celebrity we are updating. Also, use the object you just created with the updated attributes for the celebrity and pass this object into the update method as the second argument.
   • If there is an error retrieving that celebrity, call the route's next function and return the error
   • If there is no error, redirect back to the list of celebrities.

Celebrities - Done!

At this point, we have implemented all the basic CRUD actions for the Celebrity model in our app. Nice work!

Now that we've done all this good work, it's time to do it all over again, but for the Movie model. After all, what's the point of having all these celebrities if we can't make up fake movies to cast them in?

We are going to create a Movie model and implement all the same CRUD actions for this model as well. Don't worry, it's really much easier the second time around.

Iteration #7: The Movie model

Now when we've started all this good work, let's keep up strong and build all the routes for the Movie model. But first, let's create the Movie model.

The Movie model should have:

• title - String
• genre - String
• plot - String
• cast - Array of object IDs referencing the celebrity model (basically, the array of celebrities' IDs)

Steps we will follow in this iteration:

Go back and review what you did to create the celebrity model. You'll need to create a file for the model, and in that file, you'll need to create a schema for the model as well. Don't forget, you have to module.exports the Movie model.

Iteration #8: Adding new movies

Okay, the next step is to make it so the user can add new movies to the database.

Route	HTTP Verb	Description
/movies/new	GET	Show a form to create a movie
/movies	POST	Send the data from the form to this route to create the movie and save it to the database

Steps we will follow in this iteration:

Review how you did this for the celebrity model.

• Create 2 new routes, one to render page with the form on it, and one to send the data to after the form is filled out
  • In the GET route that displays the form to create a new movie (which renders the movies/new view), make sure you pass all the celebrities from your database so your users can choose which ones are in the cast of the movie you're just creating (hint: You will have to use select multiple tag)
• Make sure the form is making a POST request to the other route you just created (/movies)
• In your post route, create an object with all the info you just received from the form. (Remember, req.body)
• Use this object to create a new movie in the database and redirect back to the page with your list of all movies
• Make sure to add a link to the form on the movies index page so the user can easier navigate

Iteration #9: Listing our movies

Now that we've got some movies in the database, let's make a page where we list all our movies, just like we did with the celebrity model.

Here's the route we will be using:

Route	HTTP Verb	Description
/movies	GET	Show all movies

Steps we will follow in this iteration:

Go back and review how you did this for the celebrity model. You'll need to:

• Create a GET route that will render the file in which we will display movies (movies/index view)
• Use a database query to retrieve all the movies from your database and render the view
• Use a {{#each}} loop to display all your movie titles on that page
• Add a link to the page you just created on the home page so the user can navigate to it.

Iteration #10: The movie details page

We've got a list of all movies that displays each of their titles, but what if we want to see the other details? In our movies/index view with our list of movies, let's add links so that the user can click on any movie's title, and go to a details page of each movie. On this page, we will show all the details of that movie. Here's the route we will be using:

Route	HTTP Verb	Description
/movies/:id	GET	Show a specific movie

Steps we will follow in this iteration:

1. We need /:id part to change dynamically as we click on different movies' titles. This being said, as part of the loop that displays each movie's title, add a link that goes to the /movies/:id route with the :id replaced by the actual movie's id 🔑
2. Create the /movies/:id GET route in routes/movies.js.
3. In the route:
   • On the Movie model call findOne() or findById() method to retrieve the details of a specific movie by its ID
     • Don't forget you have cast as the array of celebrity IDs, and we need to populate() in order to get the full data about the celebrities 🎯
   • If everything is fine (.then()), render the movies/show view and pass the variable with the movie's details into the view
   • If there's an error, catch it.
4. In the views/movies/show.hbs view file:
   • Add an <h2> for the page's heading.
   • Display tags with the movie's title, genre, plot and cast.

Iteration #11: Deleting movies

Now that we have a list of movies, a movie details page, and a page to create new movies, we only have 2 features left to implement: editing celebrities and deleting them. Since deleting is simpler, let's start with that.

Route	HTTP Verb	Description
/movies/:id/delete	POST	Delete a specific movie

Steps we will follow in this iteration:

1. In the views/movies/show.hbs file:
   • Add a <form> tag that makes a POST request to /movies/:id/delete where the :id is replaced by the actual ID of the movie.
   • Add a <button> tag inside the form so that it can be submitted.
2. Create the /movies/:id/delete POST route in your routes/movies.js file
3. In the route:
   • Use the Movie model's findByIdAndRemove() method to delete the specific movie by its ID.
   • If everything is good (.then()), redirect to the list of movies page
   • If there's an error, catch it

Iteration #12: Editing movies

Final piece of our CRUD puzzle: editing existing movies.

Here are the routes we will be using:

Route	HTTP Verb	Description
/movies/:id/edit	GET	Show a form to edit a movie
/movies/:id	POST	Send the data from the form to this route to update the specific movie

Steps we will follow in this iteration:

1. Create the /:id/edit GET route in routes/movies.js.
2. In that route:
   • Call the Movie model’s findOne() or findById() method to retrieve a specific movie by its ID
   • If everything is good, render the movies/edit view
   • Pass the variable with the movie's details into the view
3. In the views/movies/edit.hbs view file:
   • Add an <h2> tag for the page's heading.
   • Add a <form> tag that makes a POST request to /movies/:id with the :id replaced by the actual movie's ID.
   • Add <input> tags inside the form for each attribute of the movie.
     • Hint: When you render the edit form, make sure each of the input fields is pre-filled with the current value of the attribute for that movie
   • Add a <button> tag inside the form so that the user can submit the form once they are done editing.
   • BONUS: Make the current cast members selected so the user knows who is in the cast currently.
4. Create /movies/:id POST route in the routes/movies.js file
5. In that route:
   • Create an object with Movie model keys and it's values should come from the form submission (which is req.body)
   • Now you can apply different methods - update() or findByIdAndUpdate() to find the movie and send the updated values to the database.
   • If there is no error, redirect back to the movie details page.

Now you can come back to the bonus part related to the celebrity model 😉.

That's it! 🏆

Happy Coding! ❤️
